For a platform meant for personnel, what is the minimum width it should have?

The minimum width for a personnel platform is established to ensure safe and adequate space for individuals to work without risking falls or the inability to maneuver comfortably. A width of 18 inches provides a basic level of safety, allowing enough space for personnel to stand, move about, and perform tasks without overcrowding. In various safety standards, this width is considered the minimum to reduce risks associated with working closely together, especially when handling tools or materials. Platforms narrower than this could compromise safety, increasing the chance of accidents.

Wider options may be preferred for enhanced safety, but the question specifically asks for the minimum width, making 18 inches the correct choice in this context.
